The Bauer Tuuk LightSpeed Edge Holder is the next generation from the legendary Tuuk family. The Edge holder sits 3mm taller in the the front and rear post so that the skate will not bottom out as quickly, therefore allowing palyers to turn tighter than ever before. The other update was the quick release runner system. Using the trigger located in the rear post, once this is fully compressed the runner will pop out in seconds and will be ready for a fresh pair of steel. This is ideal for the player who plays frequently on difference ice hardnesses, allowing them to switch out different steel sharpened for different rinks. The other advantage is in case of an emergency where a runner is broken in a game, the player won't miss a shift trying to swap out their steel.
